WILLIAM J. BARNES, OF PITTSBURG, PENNSYLVANIA.

SAFE.

SPECIFICATION forming part of Letters Patent N o. 651,288, dated J' une5, 1900.

Application tiled August 16, 1899. Serial No. 727.429. (No model.)

To all whom, t may concern,.-

Be it known that I, WILLIAM J. BARNES, acitizen of the United States ofAmerica, residing at No. 308 Oakland avenue, Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented cert-ain new anduseful Improvements in Safes; and I do hereby declare the following tobe a full, clear, and exact description thereof, reference being had tothe accompanyingdrawings, which form a part of this specification.

My invention relates to certain new and useful improvements insafe-doors; and it consists in certain details of construction andcombination of parts, as will be fully described hereinafter.

My aim is to produce a safe fitted with my improved screw-door and anyapproved timelock for use of bankers, brokers, and business men who areaccustomed to open their safes in the morning and keep them open untilbusinesscloses. This safe especially appeals to such business men onaccount of the despatch with which it can be closed and locked. Aquarter-revolution of the handles suflioes to screw the door home, andthe timelock immediatelylocks the safe and keeps it locked until thetimeset for opening. Thus in case of attempted robbery a quick man can lockthe safe in a flash and would-be robbers are completely foiled, and thisdoor litted to a burglar-proof safe becomes impregnable.

To enable those skilled in the arts to construct and apply my improveddoor, I will proceed to describe it, reference being had to the drawingsaccompanying and forming a part of this specification, in which- Figurelis a front elevation of a safe, showi ng my improved screw-door inplace thereon. Fig. 2 is a similar view showing safe-doors thrown open.Fig. 3 is a side elevation of the safe-door complete. Fig. 4 is a rearelevation of the safe-door.

In describing my invention in det-ail, similar figures of referenceindicating similar parts throughout each and every view, 1 indicates theouter plate of the door, 2 the inner plate, and 3 the circular doorproper, bearing the segmental threads 12, of which six are shown, andconstructed of such shape that a quarter-revolution of the handles 8,operating shaft, will securely close the door. This door 3, which isformed integral with the plate 2, is mounted on a 'shaft 4, whichpierces the outer plate 1 and is completed with a hand-wheel 7, suppliedwith handles 8, and a collar 5, provided with arms 6, is formed integralwith the shaft and provided with pins 9, formed with circular heads 10,the pins running in grooves 9' when the door revolves and strengtheninglthe same. The door is pivotally mounted at 14 on carrier 15 by means ofplate 11 and pin entering hollow cylinder 14, and said carrier 15 -ismounted on safe by means of hinges 1G, and the door is secured bytime-lock 13.

The operation of the door is very simple. The door -is pushed againstthe opening and the segmental threads 12 enter openings of threads 17,formed in safe,and a quarter-revolution on the hand-wheel 7 screws themhome, the said movement of the hand-wheel 7 operating mechanism withinthe lock to lock the door until the time set for time-lock to open.

Changes in the details of construction do not alter the general spiritof my invention.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is as follows:

l. In a safe-door of the class described the combination of a circulardoor bearing segmental threads, the threads designed to engage similarthreads formed in the safe, and pivotally mounted` by means of a shafton a face-plate, the said shaft having arms bearing pins designed tomove in grooves formed in said face-plate and said shaft being providedWith hand wheel and grips, designed to revolve the door, the saidface-plate being pivotally mounted on a carrier, which in turn ispivotally mounted on the safe, substantially as shown and described.

2. In a safe-door of the class described, the

combination of a circular door bearing Segmental threads, designed toengage similar threads formed in the safe, and pivotally mounted, bymeans of a shaft, on a face-plate, the said shaft having arms, bearingpins, designed to move in grooves formed in said face- ICG plate, andprovided with a hand wheel and fixed mysignature in the presence of tivosubgrip,thesaid fece-plate beingpivotally mouutscribing Witnesses. d edon a carrier, which is in turn pivotally mounted on the safe, and thedoor provided VILLIAM 'T' BARNES with a time-lock of approved design,substmi- Vitn esses: taliy as shown and described.
